1The Binary Group 4 Azides [PPh4 ]2 [Zr(N3 )6 ] and [PPh4 ]2 [Hf(N3 )6 ].

Deokar P1, Vasiliu M2, Dixon DA2, Christe KO1, Haiges R3.

Angew Chem Int Ed Engl. 2016 Nov 7;55(46):14350-14354. doi: 10.1002/anie.201609195. Epub 2016 Oct 13.

The binary zirconium and hafnium polyazides [PPh4 ]2 [M(N3 )6 ] (M=Zr, Hf) were obtained in near quantitative yields from the corresponding metal fluorides MF4 by fluoride-azide exchange reactions with Me3 SiN3 in the presence of two equivalents of [PPh4 ][N3 ]. The novel polyazido compounds were characterized by their vibrational spectra and their X-ray crystal structures. Both anion structures provide experimental evidence for near-linear M-N-N coordination of metal azides. Read More
